AITAH for telling my roommate he needs to stop “casually” being naked in common areas?

Hey there, last year I (20M) was accepted to university in Brno, and since I live pretty far away, I needed to get some kind of student housing. So for about half a year, I’ve been living with my roommate, who I’ll call Victor.

Even at the start, he mentioned that he describes himself as “very body positive” and “basically a nudist at heart,” but I figured he meant it in the sense of nude beaches, which are pretty common and popular in the area around Brno.

But since we moved in, he regularly walks around the apartment completely naked. Not just running from the shower to his room I mean cooking in the kitchen, sitting on the couch scrolling on his phone, studying, etc.

I’ve told him multiple times that I am NOT okay with stuff like that, but he usually ignores me or says something like he pays half the rent, so why shouldn’t he make himself feel at home?

I don’t know what to do. I sometimes have friends over, and he’s come out of his room naked more than once while people were there. So I basically can’t invite anyone to my flat, not my family, friends, or a date.

Obviously, I can’t move because finding a new flat in Brno is nearly impossible. I really hate living shoulder to shoulder with someone like this, and the 24/7 gaslighting has made me question whether I’m even in the right or not.

Victor is now acting cold and saying I’m intolerant and immature about the human body, threatening me with canceling our lease. I don’t care what he does in his room, I just don’t want to see my roommate naked while I’m making dinner.

AITAH for asking him to cover up in shared spaces? I know it’s his "home" too but I think that is pretty reasonable request.
